Off the top of my head (no pun intended)
You could bring the multiple lazers close to the scalp and lens from there, or you could vibtate or spin the lazers (vibration being the more viable option) to spread the beam ?
Yes, vibrations which caused minor oscillation of the beams may just work if that did not make the device too complex. I subscribe to the KISS principle in all designs.
The reading I did would suggest that you need direct contact with the skin/scalp. So how about multiple prongs of larger diameter each with a laser emitting source, perhaps conducted by fiber as you suggested.
Which might look like a sharpened pencil that has been blunted.
I fear that the Low Level Laser just doesn't have the penetration I once thought it did. However I am still not certain what I have is insufficent.
More reading is in order.
